yeah, I could finish something "playable"

Yeah, I'm so proud of myself :-) I could finish a playable game. I would have like to fix some other details, but I'm in hurry and I can't spend more time with this. I hope it work when you try it (it will be enough for me :-) ). (I tested it in a ubuntu 64, ubuntu 32 and win XP prof.; sorry I couldn't test in a mac machine) Anyway, I hope not forgetting anything in the zip file... Let me know if there is something missing or you find any bug
